The Effect of Remote Ischemic Preconditioning on Postoperative Cognitive Dysfunction in Total Knee Replacement

Start date: February 2015
Phase: N/A
Study type: Interventional

The patients were allocated randomly to receive remote preconditioning group (RIPC group, R) or not (Control group, C) using sealed envelopes with the options inside the sealed envelope of R and C before anaesthesia induction. The registered nurse who did not participate in patient care and was blind to the study performed the all randomization process. All medical staffs who involved the patient care were blind to the study. All data were collected by trained observers who were blind to the study and did not participate in patient care

NCT ID: NCT02467699 Recruiting - Knee Osteoarthritis Clinical Trials

Navigation System for in Vivo Measurement of the Kinematics of the Knee

Start date: June 2015
Phase: N/A
Study type: Observational

The knee prosthesis is a validated treatment for end-stage osteoarthritis, and this intervention usually provides a significant improvement in the quality of life of patients. However, a significant percentage of patients (up 30%) say disappointed with the outcome of the intervention. One hypothesis that could explain these poor results might be poor adaptation of the implants to the patient's anatomy, resulting in a non-physiological kinematics for the patient. Multiple studies try to obtain an individual adaptation of the intervention according to multiple criteria. The measurement of the kinematics of the knee before surgery could participate in this process.

NCT ID: NCT02456688 Recruiting - Knee Osteoarthritis Clinical Trials

Pharmacokinetics of Imrecoxib in Subjects With Hepatic Insufficiency

Start date: January 2015
Phase: Phase 1
Study type: Interventional

This clinical research study will assess pharmacokinetics and the safety of Imrecoxib in patients with impaired hepatic function as compared to healthy volunteers.

NCT ID: NCT02448407 Completed - Knee Osteoarthritis Clinical Trials

Intraarticular Injections of Platelet-rich Plasma in Pain's Treatment of the Osteoarthritic Knee

Start date: January 2014
Phase: Phase 3
Study type: Interventional

Platelet-rich plasma (PRP), due to its high content of cytokines, bioactive proteins and platelet growth factors, may contribute to diminish the pain of arthritic knee. It was also recently recognized a regenerative cell potential improving the concentration of hyaluronic acid and stabilizing angiogenesis in arthritic knees This study therefore seeks to assess the analgesic power of PRP in osteoarthritic knees intraarticularly infiltrated, and which patients would benefit most from treatment, eliminating false expectations in the rest.

NCT ID: NCT02443974 Completed - Knee Osteoarthritis Clinical Trials

Bracing to Treat Knee Osteoarthritis in Elderly

Start date: April 2015
Phase: Phase 4
Study type: Interventional

Background: Osteoarthritis (OA) is highly prevalent in the elderly, with the knee being the most commonly affected joint in this population. Knee braces are often used to prevent common problems in knees during daily activities. The purpose of these devices is to decrease pain and improve functionality. In the literature some studies have tested the effectiveness of unloader brace for valgus or varus. However, the braces most used in the investigators' clinical setting and the less costly ones have not been described in quality studies in the literature. There are only few studies on this subject and they are methodologically inadequate. There are no studies that compared the effectiveness between the knee brace with metal hinges (no alignment) and knee brace without metal hinges. Objective: To evaluate the effectiveness of knee braces on pain, function and quality of life in the elderly with knee OA. Methods: Elderly with knee OA, both genders, with pain scale 3-7cm on a 10cm pain numeric scale were included. Of the 222 patients screened, 120 met the eligibility criteria and were randomized to the groups: without metal hinges, with metal hinges or control group. The groups without and with metal hinges received knee brace and were instructed to use it in daily activities, every day, during three months. Assessment for pain (NPS), function (WOMAC and Knee Lequesne) and quality of life (SF-36) were done at baseline and after 45, 90 and 180 days by a blinded assessor.

NCT ID: NCT02429245 Not yet recruiting - Knee Osteoarthritis Clinical Trials

Single Cutting Guides System for the Installation of a Total Knee Replacement

Start date: May 2015
Phase: N/A
Study type: Observational

The knee prosthesis is a validated treatment for end-stage of knee osteoarthritis, and this intervention usually provides a significant improvement in the quality of life of patients. However, a significant percentage of patients (up to 30%) are disappointed with the outcome of the intervention. One hypothesis that could explain these poor results might be the poor positioning of implants. Individual cutting guides are produced after a CT scan response planning carried out according to the CT scan anatomy of each patient, and subsequently adapted to its real anatomy during surgery, thus theoretically better accuracy of the implementation over conventional techniques. It has been shown in the past that the navigation has been the gold standard in measuring the three-dimensional orientation of the implants during surgery, and this system is systematically used in the service for over 10 years.

NCT ID: NCT02426060 Active, not recruiting - Knee Osteoarthritis Clinical Trials

A Drug Drug Interaciton Study of Imrecoxib and Warfarin in Healthy Volunteers

Start date: January 2015
Phase: Phase 1
Study type: Interventional

The objective of this study was to determine the effects of Imrecoxib, an anti-infiammatory/analgesic agent that primarily inhibits COX-2 and not COX-1 at therapeutic doses, on the steady-state pharmacokinetic profile and hypoprothrombinemic effect of warfarin in healthy volunteers.

NCT ID: NCT02416505 Completed - Knee Osteoarthritis Clinical Trials

The Age of OrthoInfo: A Randomized Controlled Trial Evaluating Patient Comprehension of Informed Consent

Start date: September 2014
Phase: N/A
Study type: Interventional

This study is a Non-funded, Single Center, Multi-Arm, Parallel Group Randomize Control Trial. In this study, the investigators aim to evaluate the impact of a visual aid on patient comprehension an orthopedic informed consent discussion in low socioeconomic populations. The primary outcome is patient comprehension measured by a Validated Knowledge-Based Multiple Choice Questionnaire. The secondary outcomes include: Patient satisfaction and Time efficiency. The investigators hypothesize that using an Anatomic Model Visual Aid during an orthopedic informed consent discussion will improve patient comprehension, satisfaction and time-efficiency of orthopedic care.

NCT ID: NCT02413411 Completed - Knee Osteoarthritis Clinical Trials

Race and Preference for Knee Replacement: A Patient-Centered Intervention

REPAIR
Start date: May 2010
Phase: N/A
Study type: Interventional

A randomized, controlled design will be utilized to examine and compare the effectiveness of the proposed educational intervention, which includes a combination of an educational decision aid and motivational interviewing with attention control on select key patient-centered and process of care outcomes. The study sample will consist of approximately 450 African-American patients with osteoarthritis of the knee. Patients will be recruited from the University of Pennsylvania Health System and the Philadelphia VA Medical Center and will be randomized to one of the two study arms. The immediate goal of this randomized controlled trial is to assess the effect of a high-quality, evidence-based, patient-centered educational intervention supplemented with targeted counseling (motivational interviewing) on African American patient preferences, expectations, and the likelihood of achieving a referral for surgical evaluation. The long-term goal of this research is to widely implement a patient-centered educational intervention targeting African Americans who are potential candidates for joint replacement, in a national effort to reduce and ultimately eliminate racial disparities in the utilization of this effective treatment option. Study Aim:To examine the effect of the knee osteoarthritis Decision Aid (DA)/Motivational Interviewing (MI) intervention on orthopedic surgery referral rates for African American (AA) patients. Hypothesis: Compared to attention control, the DA/MI intervention will lead to higher orthopedic surgery referral rates for AA patients. Secondary aim: To examine the effect of the DA/MI intervention on the rate of knee replacement receipt among AA patients. Hypothesis: AA patients randomized to receive the intervention will have higher rates of knee replacement compared to those in the attention control group.
